Abstract
This method allows evaluating the relative adhesion strength between T lymphocytes and specific adherent target cells using a shear force in flow chambers. It is based on the measure of the resistance of conjugates formed between T cells and adherent tumor cells to shear stress in a microfluidic system. For this purpose, T cells, stained with a CellTracker probe, are added into flow channels containing a monolayer of adherent target cells and their progressive detachment under a constant shear stress is then recorded using a fluorescent microscope.
